Its got to be this fish dish that I had at the restaurant at Benedicts (hotel) in Belfast. Its not on the menu anymore but IIRC it was chunks of monkfish, seabass and salmon, on a skewer with scallops, mussells etc, with a chilli and ginger dressing. I had their garlic potatoes with it and it really was amazing, quite possibly the best meal I have ever eaten.

For interest the current menu is here:
